这是一篇关于转基因植物安全性试验的文献,其中包括转基因玉米,马铃薯,大豆,水稻,小黑麦。文献介绍了关于转基因的多项安全实验,包括90天的,长期的(多于90天, 最长到两年),多代的(2-5代)。这些实验都一致的证实转基因作物和传统作物一样安全。

题目:

Snell C, Bernheim A, Bergé JB, Kuntz M, Pascal G, Paris A, Ricroch AE., “Assessment of the health impact of GM plant diets in long-term and multigenerational animal feeding trials: a literature review,”, Food Chem Toxicol. 2012 Mar;50(3-4):1134-48. doi: 10.1016/j.fct.2011.11.048. Epub 2011 Dec 3.。

摘要:

The aim of this systematic review was to collect data concerning the effects of diets containing GM maize, potato, soybean, rice, or triticale on animal health. We examined 12 long-term studies (of more than 90 days, up to 2 years in duration) and 12 multigenerational studies (from 2 to 5 generations). We referenced the 90-day studies on GM feed for which long-term or multigenerational study data were available. Many parameters have been examined using biochemical analyses, histological examination of specific organs, hematology and the detection of transgenic DNA. The statistical findings and methods have been considered from each study. Results from all the 24 studies do not suggest any health hazards and, in general, there were no statistically significant differences within parameters observed. However, some small differences were observed, though these fell within the normal variation range of the considered parameter and thus had no biological or toxicological significance. If required, a 90-day feeding study performed in rodents, according to the OECD Test Guideline, is generally considered sufficient in order to evaluate the health effects of GM feed. The studies reviewed present evidence to show that GM plants are nutritionally equivalent to their non-GM counterparts and can be safely used in food and feed.。

松鼠的生活习性:

1、食物习性:松鼠喜欢吃素,偶尔也吃荤,素食主要以红松、云杉、冷杉、落叶松、樟子松和榛子、橡子的干果以及种子为主,荤食主要以昆虫、幼虫、蚁卵和其它小动物等为主,在食物青黄不接的情况下,松鼠另有选择。

春季吃树芽,夏季吃蘑菇、托盘和越桔等浆果,到了秋季食物极大丰富,吃喝不愁,想吃啥就有啥,但最上口的还是红松果仁。

2、繁殖习性:松鼠多在春、夏季发情,发情期大约为两个星期左右。松鼠繁殖的适龄期,雌性为8~9周龄,雄鼠为9~10周龄。

怀孕时间大约为35~40天,每年能产3胎左右,每次能产4~6只。初生松鼠体形很小,看不见东西,以母体乳汁作为全部营养需求的来源。松鼠发育很慢,生下将近30天时才睁开眼睛。至一个半月时,小松鼠才愿意到室外进行活动。

3、筑巢习性:松鼠在茂密的树枝上筑巢,或者利用乌鸦和喜鹊的废巢,有时也在树洞中做窝,除了吃野果外,还吃嫩枝、幼芽、树叶,以及昆虫和鸟蛋。秋天一到,松鼠就开始贮藏食物,一只松鼠常将几公斤食物分几处贮存,有时还见到松鼠在树上晒食物,不让它们变质霉烂。

CHEAP 只要没有将血槽用完,那么最低的评价就是CHEAP(对于CHEAP我比较陌生,因为平常我玩的不是PERFECT或者GREAT那就肯定是消失或者圣夜霜雪那两个BOSS曲直接就GAME OVER了,CHEAP并不能算是成功过关,所以既不会出现新的音乐,更不会获得鉴赏模式,所以CHEAP就相当于GAME OVER了,不过至少不会看到GAME OVER时MIKU那让人心碎的动作)。

STANDARD 据本人不负责测试统计,似乎是只要能练到整首歌曲总音符数的1/4且剩余一定的血量(这个一定不知道为什么我就是测不出来)即可达成.STANDARD的到来预示着你走向成功的第一步,因为第一次玩绝大多数人得到的都是这个评价,某些PSP老手可能可以得到GREAT(比如我..WWWWWWWWW),然后第一次能PERFECT的话那他是贝多芬徒弟+PSP宗师.STANDARD后可以开启新乐章,但是不能得到乐章的鉴赏模式,本人建议初玩游戏时不管评价把全乐章打出来再慢慢练习技巧.。

GREAT 同样是不负责测试统计,一般血槽必须是满的,且失误数(这里的失误指除COOL与FINE外的其他评价)不能超过一定数...(这里的一定数我测出来的结果似乎根据歌曲的难易度以及歌曲的旋律快慢有关,应该是10-20之间)能够达到GREAT说明对游戏已经有了一定的熟悉,对歌曲的旋律也有了初步的了解,这时可以试着玩一些不熟悉的歌曲,你会发现即使这首歌你听都没听过,之前从游戏中掌握的眼疾手快之类的技巧已经可以灵活运用了,加油突破最后的PERFECT吧!。

PERFECT 这个本人绝对负责任的告诉你,全连过关即可达成(全连的意思是节奏评价只有COOL和FINE,另外,如果你悲剧的发现右下角显示评价的地方COOL的颜色不是金黄而是血红的话,那就说明你的辛苦白费了.原因:人家叫你按圆你非得按叉,那MIKU也救不了你了不是..)最后说一句,当你能够把初音MIKU的消失和圣夜霜雪蛋定的达成PERFECT时,你已经成为神的存在了。

以上,本人辛苦的一字一字打出来.所以,望采纳。

松鼠的资料与生活习惯 英文

==================================。

The largest mammal is (blue whale)。

==================================。

The Blue Whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales (called Mysticeti). At up to 33 metres (110 ft) in length and 181 metric tonnes (200 short tons) or more in weight, it is believed to be the largest animal ever to have existed.。

Long and slender, the Blue Whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath. There are at least three distinct subspecies: B. m. musculus of the north Atlantic and north Pacific, B. m. intermedia, of the Southern Ocean and B. m. brevicauda (also known as the Pygmy Blue Whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists mainly of small crustaceans known as krill, as well as small fish and sometimes squid.。

Blue Whales were abundant in nearly all oceans until the beginning of the twentieth century. For over 40 years they were hunted almost to extinction by whalers until protected by the international community in 1966. A 2002 report estimated there were 5,000 to 12,000 Blue Whales worldwide located in at least five groups.。

More recent research into the Pygmy subspecies suggests this may be an underestimate. Before whaling the largest population was in the Antarctic, numbering approximately 239,000 (range 202,000 to 311,000).。

There remain only much smaller (around 2,000) concentrations in each of the North-East Pacific, Antarctic, and Indian Ocean groups. There are two more groups in the North Atlantic and at least two in the Southern Hemisphere.。

========================================。

The most foul-smelling mammal is (skunk)。

========================================。

Skunks (sometimes referred to as polecats) are mammals, usually with black-and-white fur, that are best known for their ability to excrete a strong, foul-smelling odor. They belong to the family Mephitidae and to the order Carnivora. There are 11 species of skunks, which are divided into four genera: Mephitis (hooded and striped skunks, two species), Spilogale (spotted skunks, two species), Mydaus (stink badgers, two species), and Conepatus (hog-nosed skunks, five species). The two skunk species in the Mydaus genus inhabit Indonesia and the Philippines; all other skunks inhabit the Americas from Canada to central South America.。

Skunks were formerly considered to be a subfamily of the Mustelidae family of weasels and related animals (where some taxonomists still place them), but recent genetic evidence shows that they are not as closely related to the Mustelidae as formerly thought.。

Skunks are sometimes called polecats because of their visual similarity to the European polecat (Mustela putorius), a member of the Mustelidae family.。

Skunk species vary in size from about 15.6 inches (40 cm) to 37 in. (70 cm) and in weight from about 1.1 lb. (0.5 kg) (the spotted skunks) to 18 lb. (8.2 kg) (the hog-nosed skunks). They have a moderately elongated body with reasonably short, well-muscled legs, and long front claws for digging.。

Although the most common fur color is black and white, some skunks are brown or gray, and a few are cream-colored. All skunks are striped, even from birth. They may have a single thick stripe across back and tail, two thinner stripes, or a series of white spots and broken stripes (in the case of the spotted skunk). Some also have stripes on their legs.。

Skunks also have a very long tail.。

===============================。

The tallest mammal is (giraffe)。

===============================。

The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal, the tallest of all land-living animal species, and the largest ruminant. Males can be 4.8 to 5.5 metres (16 to 18 feet) tall and weigh up to 1,700 kilograms (3,800 pounds).。

The giraffe is related to deer and cattle, but is placed in a separate family, the Giraffidae, consisting only of the giraffe and its closest relative, the okapi. Its range extends from Chad to South Africa.。

Giraffes can inhabit savannas, grasslands, or open woodlands. They prefer areas enriched with acacia growth. They drink large quantities of water and, as a result, they can spend long periods of time in dry, arid areas. When searching for more food they will venture into areas with denser foliage.。

Male giraffes are around 4.8-5.5 m (16-19 ft) tall at the horn tips, and normally weigh 1300-1700 kg (2900-3800 lb) Females are 30-60 cm (1-2 ft) shorter and weigh about 200-400 kg (400-800 lb) less than males. Giraffes have spots covering their entire bodies, except their underbellies, with each giraffe having a unique pattern of spots.。

==============================。

The smallest mammal is (shrew)。

==============================。

Shrews are small, superficially mouse-like mammals of the family Soricidae. Although their external appearance is generally that of a long-nosed mouse, the shrews are not rodents and not closely related: the shrew family is part of the order Soricomorpha. Shrews have feet with five clawed toes, unlike rodents, which have four. Shrews are also not to be confused with either treeshrews or elephant shrews, which belong to different orders.。

Shrews are distributed almost worldwide: of the major temperate land masses, only New Guinea, Australia, and New Zealand do not have native shrews at all; South America has shrews only in the far-northern tropics, including Colombia. In terms of species diversity, the shrew family is the fourth most successful of the mammal families, being rivalled only by the muroid families Muridae and Cricetidae and the bat family Vespertilionidae.。

All shrews are small, most no more than mouse size. The largest species is the House Shrew (Suncus murinus) of tropical Asia which is about 15 cm long and weighs around 100 grams[citation needed]; several are very small, notably the Etruscan Shrew (Suncus etruscus) which at about 3.5 cm and 2 grams is the smallest living terrestrial mammal.。

In general, shrews are terrestrial creatures that forage for seeds, insects, nuts, worms and a variety of other foods in leaf litter and dense vegetation, but some specialise in climbing trees, living underground, in the subniveal layer or even hunting in water. They have small eyes, and generally poor vision, but have excellent senses of hearing and smell. They are very active animals, with voracious appetites and unusually high metabolic rates. Shrews must eat 80-90 per cent of their own body weight in food daily. They are not able to hibernate.。

The only terrestrial mammals known to echolocate are two genera (Sorex and Blarina) of shrews and the tenrecs of Madagascar. These include the Vagrant Shrew (Sorex vagrans), the Common or Eurasian Shrew (Sorex araneus), and the Northern Short-tailed Shrew (Blarina brevicauda). The shrews emit series of ultrasonic squeaks. In contrast to bats, shrews probably use echolocation to investigate their habitat rather than to pinpoint food.。

===============================。

The fastest mammal is (cheetah)。

===============================。

The cheetah (Acinonyx jubatus) is an atypical member of the cat family (Felidae) that is unique in its speed and stealth, while lacking climbing abilities. As such, it is placed in its own genus, Acinonyx. It is the fastest land animal, reaching speeds between 112 kilometres per hour (70 mph) and 120 kilometres per hour (75 mph) in short bursts covering distances up to 460 metres (1,500 ft), and has the ability to accelerate from 0 to 110 kilometres per hour (68 mph) in three seconds, greater than most supercars.。

The cheetah's chest is deep and its waist is narrow. The coarse, short fur of the cheetah is tan with round black spots measuring from 2 centimetres (0.79 in) to 3 centimetres (1.2 in) across, affording it some camouflage while hunting. There are no spots on its white underside, but the tail has spots, which merge to form four to six dark rings at the end. The tail usually ends in a bushy white tuft. The cheetah has a small head with high-set eyes. Black "tear marks" run from the corner of its eyes down the sides of the nose to its mouth to keep sunlight out of its eyes and to aid in hunting and seeing long distances.。

The adult cheetah weighs from 40 kilograms (88 lb) to 65 kilograms (140 lb). Its total body length is from 115 centimetres (45 in) to 135 centimetres (53 in), while the tail can measure up to 84 centimetres (33 in) in length. Males tend to be slightly larger than females and have slightly bigger heads, but there is not a great variation in cheetah sizes and it is difficult to tell males and females apart by appearance alone. Compared to a similarly-sized leopard, the cheetah is generally shorter-bodied, but is longer tailed and taller (it averages about 90 centimetres (35 in) tall) and so it appears more streamlined.。

Some cheetahs also have a rare fur pattern mutation: cheetahs with larger, blotchy, merged spots are known as 'king cheetahs'. It was once thought to be a separate subspecies, but it is merely a mutation of the African cheetah. The 'king cheetah' has only been seen in the wild a handful of times, but it has been bred in captivity.。

(The fastest sprinting speed is cheetah while the fastest running speed is a type of the antelope)。

Squirrel control treatment [Edit this paragraph] squirrel's brief introduction 。

Chinese name: squirrel 。

English name: Squirrel 。

Scientific Name: Sciurus vulgaris, 。

Generic: rodents, squirrels suborder, squirrels Branch, squirrels are 。

Personality: gentle, sweet, cute, docile, attractive, very hard-working. 。

Characteristics: a big long hairy tail. 。

Distribution: country of origin is China's northeast, northwest and Europe, except in Oceania, the all over the world are distributed. Broader distribution of squirrels in the whole boreal forest areas could be seen. In China is mainly distributed in three provinces in Northeast China, northeastern Inner Mongolia, northern Hebei and Shanxi, Ningxia, Gansu, Xinjiang and other provinces and regions of the mountain; abroad from Russia's Far East, Japan, North Korea, Mongolia, the north, the west has been distributed to Western Europe. In coniferous forest, the squirrel is not every year a lot of its numbers, based on the number of winter conifer seed for the transfer; because of its food-based plant seeds and fruits, seeds and sometimes accounted for more than 90%; and spruce seeds was not a good harvest every year in poor harvest years pineal, the squirrel will move to places with more food foraging; and at food-rich years, it will be a substantial reproduction. Propagation of a lot of quantity. 。

(Also can refer to the nine-year compulsory education in Shanghai, the first semester of sixth grade (for this) the Chinese book, the seventeenth class is Writing Buffon squirrel) [Edit this paragraph] squirrel morphology 。

Shape is usually medium-sized, are boreal coniferous forest and mixed forest in a typical representative of animals. Squirrels maxillary molars for 5, 4 mandibular, mandibular molars on different quantity. Before the hind wing without skin. Limbs strong, toes have sharp claws, claw end was hook, weight is usually at around 350 grams, females than males slightly heavier. Squirrels dignified posture and light, body grow about 18-26 cm long, thick tail, tail length for more than two thirds of body length, but not body length. 。

Tail long and fluffy hair density, and front and rear limbs were longer adequate, but shorter forelimbs than hind limbs. Auricular developed, when folded up before the eyes, ears in winter with a group of black long-haired-side beam. Body back from the rostral to the tail base, the lateral side and limbs are brown gray,毛基black, brown or gray Maojian. Abdomen from the rear under the collar to tail base, medial limbs are white. Dorsal and ventral tail was brown-black,毛基gray, brown Maojian black. Kiss the Ministry of the cheeks and under the color background such as Britain, but the partial青灰, ear shell and gray winter hair straight black hair with large clusters. Individual differences in color greater for Green gray, gray, brown gray, dark gray and dark brown and so on. With the regional differences in coat color also changes, such as the color of Liaoning partial gray squirrel, and squirrel in southern China than the black color. In addition, the coat color is also affected by seasonal effects of winter hair gray or taupe, summer hair black or dark brown. 。

Very cute squirrel squirrels living habits of the ears and tail hair is especially long, able to adapt to the tree of life; they use like a long hook the claw and tail hung upside down on tree branches. At dawn and evening, will leave the tree to the ground on predation. Squirrels in the fall to find abundant food, we will make use of tree holes or burrow in the ground, storage of fruit, such as food, soil or fallen leaves at the same time to block the hole. 。

Summer red squirrel body hair, will be replaced in the fall into winter and gray hair closely cover the whole body. Newborn squirrel, hairless body, eyes are also unknown, eight days after birth, before the beginning of long-haired, 30 days after that open your eyes, 45 days can be hard to eat the fruits of action become very agile. Squirrels are very tame master a small guy, we have to treat them gently, so that you are dead set on it will definitely not hurt your teeth. Of course they will use teeth gently nibble your fingers, and your playing, the feeling will be very itch, this is your kind express it. 。

Squirrels in the dense nests on tree branches, or the use of crow and magpie nest of waste, and sometimes also make nest in tree holes; them apart from eating wild fruit, but also eat young shoots, bud, leaves, and insects and birds eggs. First to fall, the squirrel began to store food, a squirrel often several hours a few kilograms of food storage, and sometimes see squirrels in the trees drying food, not let them rotten metamorphism. In this way, in a cold winter, squirrels have nothing to worry about eating. 。

Squirrels strong children, which, like other rodents, has a sophisticated early, quick propagation characteristics. Between January and February each year, male and female squirrels started to love, male thick tail swing jump up at crown chase females, when the female is excited enthusiastic quest. Oestrum about continuation of two weeks, during which male and female is almost inseparable. Females 35-40 days of pregnancy产崽generally yield two births each year, sometimes 3 children. The first year of child-bearing female, every 3 births -6 baby baby, 2 years after the births of each child can be 5 baby baby -10. Newborn cubs smooth hairless body, red, eyes closed, body weight at 7 grams -8.5 grams, body length, 5.6 centimeters, 2.4 centimeters long tail. Born rats 8-9 months of sexual maturity, that is, the first 2 years to be breeding spouse. 。

Squirrels enjoy vegetarian, occasionally吃荤. It's vegetarian mainly Pinus, Picea, Abies, Larix, Pinus sylvestris and hazelnut, acorn nuts, and seeds of the main;荤食mainly on insects, larvae, ants eggs and other small animals, such as the main. Gap in the food, the squirrel was another choice. Eat tree buds in spring, summer, eating mushrooms, such as pallets and Vaccinium berries, in the autumn abundant food, eat or drink to worry about, think what he吃啥on, but the most catchy or Korean pine nuts. Turning to mining pine squirrels this is the champions, no matter how high the trees, where long cones, squirrels can eat to口到. Specific process is: it's ripe cones gnaw first floor, and then down from the tree, like the primates, as before扒开foot cone scales, seed coat咬碎, remove the seeds, to pine for food, it is It is interesting that when squirrels are scared to lay down their food not easily, but to escape cone mouth. 。

Squirrels extremely well-developed sense of smell, it can accurately identify the pine nuts is empty, all松塔sharp squirrels to give up on the seeds were all non-kernel, although this has not bitten seed shell open, squirrels, or one olfactory glance. Squirrels also store food instinct, the fall of ripe red pine, the squirrel ran around their mouths, pine was transported to a safe place to hide,几粒or a pile of dozens of tablets, buried in the ground, has been reserved for winter food. Although winter snow covered the earth, but the squirrels still no effort to find the hidden food, the individual also has the omission can not be found. However, it is because buried in the ground to help find missing koraiensis seed spread and dissemination of, and promote the natural regeneration. 。

Squirrel distribution is very broad, almost throughout the entire forest. The number of its species, to a large extent depend on the abundance of food less. If food abundance for several consecutive years, the number of species will be markedly increased, especially in the pine harvest years, people living outside the squirrels also migrated into this partnership to help set up the second year in situ reproduction, thus increasing quantity; if the region pine harvest, squirrels will be relocated his family to find another habitat, resulting in dramatic reduction in the region. Squirrels such as food abundance apologize to determine the number of species behavior, it is技高一筹, it not only helps to propagate species but also to widely distributed species. 。

Squirrels living habits of different other animals, it is like in broad daylight, in particular more active in the early morning, usually at the tree trunks and branches of a tree to jump between the channeling go, one will be feeding, one would play, let their hair down, so uncomfortable. Habits of squirrels do not hibernate, but in the beginning of winter frost winter season, but also not very active cold chills. Especially the severe winter weather blowing smoke out of Waterloo Gun shorter, usually about 9:30 out of Activity 1 hour -2 hours; 13:00 minutes and then come out Events 1 hour -2 hours, other times to stay fixed nest . Squirrels have a habit that no matter how cold the weather, it did not nest at feeding, but sitting on tree branches, for朝阳, forelimb with food into the mouth, chewing with relish to taste, and sometimes listen to竖耳side, sometimes turning his eyes look around, comical manner, it is laugh. 。

Although squirrels are rodents in a larger, because it does not at the top of the food chain, so it is still the threat of predators, are a type of carnivorous birds of prey, such as sables, incense ferret, Green ferret, ferret Ling,黄鼬and so on and owls, golden eagles and so on. Another major cyana and crows are they during the breeding season, to gain the upper hand on the young squirrels. Former enemies from a sense of squirrel species multiply health benefit, because the pursuit of natural enemies to are old, weak,病体. Then a natural enemy is unhelpful. 。

It is not only the image of a squirrel cute and, more importantly, the economic value of well-known squirrel. Squirrel skin has always been for the bulk of Heilongjiang Province, one of the wild fur, in the past are an important export product. Paper squirrels can do leather, scarf, hat, tail hair brush, etc. can be produced. In recent years, Korean pine forest because of reduced, which led to squirrels for food production in red pine decline in the number of squirrels also be reduced. At present annual output of less than squirrels Paper 20000, history on the highest Muzenda 185,000, can be seen that the number of squirrels have been rare, should take measures to strictly protect. [Edit this paragraph] the breeding habits of squirrels 。

Squirrels in about 1,2 months each spring estrus, estrus around for about two weeks. Age squirrels began breeding period, females for 8 ~ 9 weeks of age, male for 9 ~ 10 weeks of age. On squirrels, the fall also have a heat period. In the non-breeding season, male and female sexual adult must occupy the place, respectively, as the scope of activities of their own lives. In the wild, females must protect an area of the site are for the protection of food, its not allow other individuals to enter the same race, same is true for males. However, during the breeding season, it is obvious that the area of deregulation of the scope of protection, permit access to males. Estrus, the female individual and loss of appetite, increased activity, irritability, was excited state; at rearing under conditions of reproduction, we have to select able-bodied, excellent gloss color, a good mental state, loss of appetite exuberant individual. Of males breeding requires a strong ability to sexuality; while females require strong maternal instinct, the number of many births, lactation sufficient individual. Breeding when one female or one hung polygyny mating methods, squirrels around the time of pregnancy for 35 ~ 40 days early in April to enter the lactation period, litter size 3 times each year about each productive 4 ~ 6. As long as adequate food, squirrels breeding female individual will be able to more individual, have a strong reproductive capacity. The beginning of the baby born to mother's milk as the source of all nutritional needs, therefore, at this time should be special attention to the nutritional status of the mother, when a small squirrel just gave birth to very small, invisible things, the development is slow, gave birth to nearly 30 days Open your eyes only; to one and a half months, the small squirrels before they are willing to outdoor activities. 。

Squirrels in small open eyes will not open, the hold keeping squirrels away from the mother will become intimate with people. Suction feeding initially in hot milk (30-40 ° C), daily 3-5 times. Gradually replace the milk soaked bread or other soft food. Even long after the initial feeding into, as long as have the patience to train slowly, and people will be very close, climb onto the main feed. [Edit this paragraph] squirrel species type 。

According to the living environment of different Squirrel Branch is divided into tree squirrels, ground squirrels and rock squirrels and so on. All over the world are 212 kinds of near 35, China has 11 genera 24 species, one of rock squirrels and lateral stria Sciurotamias two kinds of animals are endemic to China. 。

Many different types of squirrels, there are about 240 kinds all over the world, China has 26 kinds. Living in the woods one of the squirrels, in our country all over the Northeast and North China is very common, and thus is also called the ordinary squirrel. Its slender body, body hair is gray, dark brown or russet, also known as gray squirrel so. 。

Common squirrel has three types: 。

1, red-bellied tree squirrel: 。

Red-bellied tree squirrel, also known as "erythraeus" mountain people also call it "on the mouse." Is a medium-sized arboreal squirrels. 。

Size: 19 ~ 25 cm 。

Weight: 280 ~ 420 grams 。

Features: kiss short, ears small and round, thick neck 。

Red-bellied tree squirrel is mainly dwelling in the forests, the life habits and chinchilla, some similar to many hi morning, faint activity, diet mainly feeding a variety of nuts, such as pine, chestnut and berry-based, but also eat a variety of leaves, young shoots, flower and bird eggs, nestlings and insects. 2 annual breeding times producing 3 ~ 4 Aberdeen, Aberdeen 2 in the majority. 。

2, long kiss squirrels: 。

Leiocassis squirrels, also known as "Red-billed squirrels." 。

Size: 20 ~ 25 cm 。

Characteristics: slightly short limbs, tail long and thin, short and fluffy tail hair, back hair was taupe, abdominal hair as gray 。

Leiocassis squirrels generally live in dense forest, the habits of squirrels in general little difference, but not entirely arboreal, often to the ground, fallen trees and haystacks in search of food, morning, twilight hours of the most active. 。

3, Sciurotamias 。

Sciurotamias also known as "rock rat", "finishing" to shape some like red-bellied tree squirrel. 。

Size: 20 ~ 25 cm 。

Tail length: 15 cm 。

Features: great auricular obviously, a little short limbs, tail fluffy hair, sparse hair was back Green gray, abdomen and limbs, the medial gray hair yellow, lower jaw is white. 。

Sciurotamias the habitat area in the mountains, rocks, rock squirrel while climbing in the trees, but mainly between rock habitats are also generally nesting in the inter-岩隙. Sciurotamias daytime activities, mainly on wild fruit, or plant seeds for food, such as nuts, walnuts, apricots, etc., but sometimes food crops, forests are a black beast. 。

Other types

6. Jinhua rat

Size: 15cm tail length is about 12 cm 。

Place of Origin: Northeast Asia, Hokkaido 。

Eating habits: omnivorous plant-based 。

Longitudinal section in the back there are several patterns of small squirrels. Just leave the nest of small squirrels, with parents keeping separate, it is easy to domesticate. Because of the quick action, care should be taken when feeding it take to escape. Cage ready to be higher, at the same time in order to avoid lack of exercise, smoking cage wheel vehicles should be prepared to allow squirrels to play sports.巢箱installed simultaneously. As a hiding place in nature have the phenomenon of hibernation, if kept in the warmth of the interior, that does not have to hibernate. Because of less heat in summer when the cage should be moved to a well-ventilated place. 。

7.夷松shrimp rat 。
